First off, I look forward to reading through the forums. I wasn't able to view topics until I registered. I've been on here multiple times (reading and dreaming) since.
Background (I'll try and keep it short):
I first heard Klipsch speakers at my brother-in-law's house. He had just purchased a 5.1 system with Quintet speakers and a Klipsch sub. I wasn't so much focused on the stage, semblance, etc. but more the pure volume and clarity these speakers had. It started at an early age, but I like my music/movies LOUD (drives my wife crazy - Ha!). Most speakers I've owned (all low-fi) couldn't pump out the volume without distortion like the Quintet system was doing. From that point forward, I wanted to own Klipsch speakers. Fast forward a few years, and I'm currently working on house plans to custom build a house. This house will undoubtedly have a dedicated theater/music room. How big? I'm not sure, yet. The cool thing is it allowed me to start piecing together a surround sound setup. At this point in time, I definitely have to adhere to a budget. All of our free money is going towards building the house. So, I've been scouring Craigslist and Goodwill until I've put together my first 5.1 system. Over time, I plan to keep scouring the web and will replace speakers/receivers as I find better ones.
Mains: KG5.2 ($250 on Craiglist)
Center: RC25 ($80 with the RB25's on Craigslist)
Sub: Proficient Audio Systems S12 ($52 on Shopgoodwill.com)
Receiver: Onkyo TX-SR607 ($40 on Shopgoodwill.com)
I think this system sounds really good with music/movies. I really don't have to use the sub for a majority of what I watch/listen to. It's crazy how much bass comes from one active 10" woofer. The question I have is regarding higher volume. I can push the volume to a point where I hear distortion. I mean, it's loud, but it's not LOUD. I may be expecting the speakers to do something they're not made to do, but all of the reviews I've read say these things will "boogie" when you want them to. Honestly, I want speakers that will go loud enough that I have to stop the volume increase due to listening discomfort rather than me stopping the volume increase based on distortion. The KG5.2's are completely stock in regards to diaphragms and crossovers. Would titanium tweeter diaphragms fix this issue? Do I need a better receiver (I had an older Kenwood hooked up to them at one time and noticed the distortion, as well)? Should I keep an eye out for different Klipsch speakers that would better satisfy my quest for volume? I appreciate any insight you guys can give me.
Back working on these 6V6PP mono amplifiers again. After listening to them (last spring or whenever) with the circuit used and the Admiral output transformers, the GF and I weren't very impressed. So I swapped back in the original Magnavox output transformers, and adjusted for feedback the conventional way. Better, but not by much.
Most the issue is hash/hiss noises. These original Magnavox 6V6 PP console amplifiers had shields for the driver tube.
One had a 6AN8 driver tube with a shield. The other had a 12AX7 which had a strange lead cover for it...a type of shield.
So I have one amplifier with a new socket and shield, amp "Y"...another thing is I had each plate of 12AX7 up around 285 volts for each amp, with a cathode voltage of 2.3 volts. Probably a bit excessive.
I also reworked the driver circuit using the Gillespie driver circuit for the Magnavox 9300. I may have to noodle with a couple values for the feedback and HF compensation for the 12AX7 when I look on a scope.
The Gillespie driver/paraphase (floating) circuit uses a higher value plate resistor for 12AX7 (actually 6EU7, same thing but 6.3 volts). That dropped the plate voltage down to 170-173 volts, with cathode voltage at 1.1-1.5 volts. That should help with noise I would guess.
The original Magnavox circuit for 164BA has two 100 ohm resistors forming a virtual CT/divider, and the voltage is taken from the center-tap and applied at the cathodes of 6V6. I omitted this with the Dynaco circuit I copied.
With amp "Y", and went ahead put the divider back in, with the voltage from the CT to the cathodes of 6V6.
If I recall, this same technique is used with my Maynard 6AQ5 SEPP amplifier.
Impending rain yet again.

Basically, I was walking through the plant with PWK and noticed one sitting in a small room. I just asked him what it was and he said "Dixielander." I didn't ask further as we were headed to the lab to listen. For years, both due to the name "Dixielander" and the design, I assumed it was one of PWKs. It was years later when I found out it was a Jack Frazier design. I had found out straight from PWK that Jack was the only other speaker designer he fully believed in, so my own first speakers were Monte Carlos as Heresy was the cheapest think in the Klipsch lineup at the time and out of my range. I finally got rid of them about a year ago as they were in dreadful shape...but I have 4 more! Frazier stuff is incredibly good and PWK approved. Enjoy!
Editing to mention that Frazier's blend about as seamless as possible with Klipsch in multi-speaker arrays. Dixieland would make a fine center speaker, or a pair in the rear, with La Scala, Heresy, Cornwall, K'horn's in the front.
That has been suggested and is exactly what he needs to do but he will need some sort of RCA splitter as there appears to only be one set of pre-outs on his integrated unit and they are connected with jumpers. If the jumpers are removed I'm fairly certain it removes the onboard amp from the processor, which is a nice feature to have on an integrated amplifier, leaves the opportunity open for external amplification, or, in this situation the ability to send the signal to a subwoofer.
